A stop is a sound that involves a complete closure in the vocal tract so that sound cannot escape the oral cavity. This closure can be in the oral or nasal cavity. The release of this closure creates a burst (which can be accompanied by aspiration) that is quite distinctive on the spectrogram.
In Gaelic, the oral stops are [pʰ, tʰ, kʰ, p, t, k]; these are written as p, t, c, b, d, g, respectively. The nasal stops of Gaelic are [m, n, N, ŋ], which are written as m, n, nn, and ng.
